According to my calculations, that would total about $1.80 per tank.

It is an aggressive fish and is usually kept one male per tank.

That is not a problem, but there must be at least 5-6 individuals per tank because arowanas are very aggressive towards each other.

His force was left with two shells per tank.

They are barbecuing instead and saving the $70 per tank it now costs to fill up their minivan.

The cost could range between $25,000 and $100,000 per tank, according to state environmental officials.

The average cost per tank, in the first batch, was 45 million pesetas (642,800 dollars).

Cost per tank increased during the second batch to 62 million pesetas (885,700 dollars).

Only one specimen should be kept per tank, as it is aggressive with members of the same species.

Not so if the rate is per tank, which can get to be quite costly.
